Computer locking up

[Frein]

This sounds very much like the soldering issue that commonly happened with the 8800 series cards (mine included). The fix is to bake the card in an oven. Follow these instructions: http://www.overclockers.com/forums/s...d.php?t=606658

Thanks. I replaced the psu with a 750w pc power & cooling, big psu to fit in a micro atx case, but I got it. First boot and it did it again. I'm 99.9% sure it's the video card. I think I'll give evga a call tomorrow. I forgot to register it, but I have 2 motherboards and 3 other video cards registered, so hopefully they'll be understanding.
